I stumbled across an article on about using DNA to tag clothing with a unique, non-copiable marker to combat theft and counterfeiting. Seems intriguing.

A little more than two years ago U.S. textile manufacturers asked the federal government for help in finding a cost-effective "tracer"—something that could authenticate their products and track them around the world. Cass Johnson, president of the National Council of Textile Organizations, says the object was to fight counterfeiting and transshipments—or goods imported into the U.S. bearing a false country of origin, usually to get around import quota limits. (Some apparel importers get preferential tax treatment if they use U.S. fabrics and yarns.) Researchers at Oak Ridge National Laboratory in Tennessee began looking into textile-marking systems that could be carried within the cloth itself rather than on a separate tag. Right now three methods are being tested: Applied DNA's marker, nano-barcodes (submicroscopic stripes attached to a rod many times thinner than a human hair), and quantum dots (artificial atoms that give off colors in the presence of a special light). Of the three, Applied DNA's marker is the furthest along in development.
